BMAT questions with verified answers
absorption of EM waves causes: Ans✓✓✓ - heating - e.eg in a radiant
electric heater or oven
- electrons in the surface to vibrate at the frequency of the wave - e.g.
in radio reception
- ionisation - e.g when X-rays/gamma-rays are absorbed by human
tissues
acceleration of free fall Ans✓✓✓ an object falling freely due to gravity
falls with an acceleration that is numerically equal to the gravitational
field strength
acceleration= Ans✓✓✓ change in velocity/time
ADH Ans✓✓✓ controls how much water is lost by the kidneys
adrenaline Ans✓✓✓ - released by adrenal glands in response to
stressful/scary situations
aerobic respiration equation Ans✓✓✓ glucose + oxygen --> carbon
dioxide + water + energy
ammeter Ans✓✓✓
,anaerobic respiration in animals Ans✓✓✓ glucose --> lactic acid +
energy
angles of incidence and refraction Ans✓✓✓
antibodies present in blood groups Ans✓✓✓ A = b
B=a
AB = -
O = a and b
apparent weightlessness Ans✓✓✓ experienced when we have weight
which causes us to accelerate at the acceleration of free fall
applications of radiation Ans✓✓✓ - sterilisation
- medical tracers
- thickness gauge
artery Ans✓✓✓ No valves along the length of the vessel.
Narrow lumen (space inside vessel).
Thick walls made of muscle and elastic tissue to prevent bursting.
Carries higher pressure blood.
Usually carries oxygenated blood (except pulmonary artery).
,average speed= Ans✓✓✓ total distance/total time
axon Ans✓✓✓ long section of a neutron through which electrical
impulses travel
battery Ans✓✓✓
benefits of genetic engineering in medical applications Ans✓✓✓ -
GMOs can be used to produce medicines such as insulin to treat
diabetes
- GMOs have been used in the development of vaccines, e.g.
recombiant hep B vaccine produced by GM baker's yeast
- GM pigs developed by human organs
- GM insects created to reduce spread of certain diseases, e.g. malaria
- genetic modification of human cells can be carried out to provide
possible cures for genetic diseases such as cystic fibrosis
benefits of iPSCs Ans✓✓✓ - the treatment of conditions in place of the
more controversial embryonic stem cells
- stem cells produced from a patient's own body cells should not be
rejected as foreign
- learning more about specific diseases by culturing cells from a patient
in the laboratory and then inducing them to differentiate into a specific
cell type which can be studied, e.g. brain cells cultured to learn more
about Alzheimer's disease which affects the brain
, - testing the effectiveness of drugs in cell culture before they are used
in a patient.
calculate frequency and wavelength in EM spectrum Ans✓✓✓ speed
of light = frequency x wavelength
Can conductors become charged by friction? Ans✓✓✓ Yes, if they are
insulated from their surroundings, otherwise the charge will leak away
cell Ans✓✓✓
centi- Ans✓✓✓ 10⁻²
central nervous system Ans✓✓✓ made up of the brain, which is
protected by the skull, and the spinal cord, a collection of nerves that
run down the spine through the vertebrae. Nerves from the receptors
in the sense organs bring impulses to the spinal cord which then sends
them to the brain for processing. The brain interprets the impulses and
then responds by sending an impulse via the spinal cord to the nerves
which connect to the organs and tissues of the body.
change in momentum= Ans✓✓✓ external resultant force x time
characteristic properties of a gas Ans✓✓✓ - fluid
- high compressibility
